CyberWar?

Bruce Schneier has a fascinating opinion piece up on, of all places, CNN.  A teaser:

That's the key question: How much of what the United States is currently doing is an act of war by international definitions? Already we're accusing China of penetrating our systems in order to map "military capabilities that could be exploited during a crisis." What PPD-20 and Snowden describe is much worse, and certainly China, and other countries, are doing the same.

All of this mapping of vulnerabilities and keeping them secret for offensive use makes the Internet less secure, and these pre-targeted, ready-to-unleash cyberweapons are destabalizing forces on international relationships. Rooting around other countries' networks, analyzing vulnerabilities, creating back doors, and leaving logic bombs could easily be construed as an act of war. And all it takes is one over-achieving national leader for this all to tumble into actual war.

It's time to stop the madness. Yes, our military needs to invest in cyberwar capabilities, but we also need international rules of cyberwar, more transparency from our own government on what we are and are not doing, international cooperation between governments and viable cyberweapons treaties. Yes, these are difficult. Yes, it's a long slow process. Yes, there won't be international consensus, certainly not in the beginning. But even with all of those problems, it's a better path to go down than the one we're on now.
